JAMES MAURIUE Nl llVALL, OF SEAFOlt'llll. ENGLAND.

Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed December 22,1904. $erial No. 237,968.

Be it known that lJmuns Anatole NmvALL, engineer, M. I. M. E., a subject of the King of (i reat Britain and Ireland, and a resident of 11 Beaconsh'eld road, Seaforth, in the county of Lancaster, England, have invented certain new and useful Improvements in Fastenings for Doors, \Vindows, or the Like, of which the following is a specification.

This invention has reference more particularly to a fastening for doors, and has for its object to provide a fastening by means of which the door may be opened to some extent by the oceu pier of a room say for the purpose of ventilation-but without permitting the door to be opened farther from the outside.

i will describe my invention with the aid of the accompanying drawings, in which-- Figure 1 is a sectional elevation of the appliance as fitted in connection with a door, the door being closed. Fig. 2 is a front view. Fig. 3 a view showing the door ajar and secured in this position.

l'teferring now to the drawings, 1/ represents the door, and the jamb or door-frame. v is a bracket secured to the jamb 7, to which an arm f is pivoted, as at c.

(j designates a bolt or projection which forms an extension of the loose sleeve 1/, carried by arm f. As shown, the bolt (1 is adapted to slide in and out of the guide-plate g, fitted to door (1. This guide-plate is slotted and is closed at one end, /i and i being the closed and open ends, respectively. The bolt-head is .L or ball shaped in order to prevent its lifting out of engagement with guide-plate r A stop K' is lixcd in the end of arm f by being driven or secured therein, and through this stop passes a sliding rod A stop III is socured to the inner end of this rod, and between the stops Z' and 11/ is coiled a spring j. On the outer end of the rod 1 outside the arm f is secured a head Z". By this arrangement the sliding bolt 6 is prevented from accidentally moving entirely out of engagement with the guide as the part Z" prevents it; but of course slight pressure on the part of the person using the fastening will entirely free the bolt from the guide 7.

n a pinching-screw by means of which the bolt may be secured in any desired position on the arm f, so that the amount of opening of the door r1 may be regulated as required.

0 represents rubber sheathings which may be employed to prevent rattling of the appliance.

In use when the door is tightly closed the bolt on the pivoted arm f is placed in engagement with the guide r as shown in Fig. l of the drawings, and by securing the bolt by the pinching-screw the door may be locked in this position.

In some cases I may provide a book on sleeve 1/, which is adapted to engage in a hole 1 in 1/, by which the door may be hooked open and unhooked from the outside.

To open the door for ventilation, bolt 1' is released by unscrewing 1/, when the door may be opened to any desired extent (the amount of opening being regulated by the length of arm f) and secured again by the pinchingscrew 1). To free the door entirely from the fastening, the door is first closed, when bolt I may be slid out of guide 1/ and the arm 7" turned about its pivot out of the path of the door.

In some cases the pivoted arm may be attached to the door and the guide attached to the jamb or door-frame.

It will be seen that it is only possible to remove the fastening when the door is entirely closed.

\Vhile my invention has been described as beingmore particularly applicable as a fastening for doors, it may also be employed in connection with windows as French windows or as a fastening in connection with other hinged or pivoted articles.

Having now described my invention, what I. claim as new. and desire to secure by Letters Patent, is

1. A fastening for doors, windows, or the like, comprising an armf pivoted as at C; a sliding bolt w carried by sleeve (Z; a guide-plate 1/ closed at one end and open at the other end, with which said bolt (f is adapted to engage; a pinching-screw n; a springjdisposed around a rod l between a lixed stop A and a stop 111 connected with said rod and a movable head Z" also connected to said rod for the purpose described.

2-. A fastener for doors, windows, or the like, comprising an arm f pivoted as at o; a sliding bolt (1 carried by sleeve (7; a guideplate 5 closed at one end and open at the other end with which said bolt I is adapted to engage; a pinching-screw u; a spring jdisposed around a rod between a lixed stop I and a stop 11/ connected with said rod a movable head 70 also connected to said rod Z and rubber sheathings as u, for the purpose Specified.

3. A fastening for doors, Windows, or the like, comprising an arm f pivoted as at O; a sliding bolt (2 carried by sleeve (Z; a guideplate g closed at one end and open at the other end, and With which said bolt 0 is adapted to engage; a pinching-screw n; and a part 70 controlled by a spring 7' for the purpose described.

In testimony whereof I have signed my name in the presence of two subscribing Witnesses.
